MacBook looses keyboard responsiveness and then dies
My sister's laptop suddenly lost responsiveness with the keyboard one day - the keys didn't do anything anymore. The mouse was still active though, so I let her use an external USB keyboard until I could figure out what was going on. She gave me the laptop to fix today, and now I can't get it to boot. Sometimes the MagSafe light turns on, but most of the time it doesn't, and pressing the power button doesn't get any response out of it. I tried reseating the RAM, but that didn't work.
I managed to back up the hard drive before it died, but my sister really needs this computer (or a quick replacement), since it is her only computer. Just from the symptoms I would guess it's logic board failure, but I'm really hoping it's something I can fix.
As soon as my own laptop finishes backing up, I'm going to attempt swapping hard drives and see if that does anything (though I highly doubt it).
What can I try?
UPDATE After swapping out the hard drives, I was able to boot her hard drive in my machine. I'm doing a disk repair right now, might try the keyboard swap later.
Is this a good question?
